DAMPER FRAME.

Application filed August 15, 1927. Serial N'o. 213,079.

This invention relates to improvements in dampers and draft regulators for stove pipes, and relates more particularly to the manner of attaching the draft regulator to the stove pipe.

A principal object-of the invention is to provide means for attaching a damper frame to a stove pipe without the use of bolts, nuts,

screws or the like.

A further object of the invention is to provide in a draft regulator means for detachably securing the same to a stove pipe.

A still further object of the invention is to provide in a draft regulator and damper control for astove pipe, means for concealing the attaching means to said pipe.

lVith the above and such other objects in view as may hereinafter more fully appear, I have invented the device illustrated in the accompanying drawings, in which Figure l is a side view of a stove pipe section, partly broken away, embracing my invention.

Figure 2 is a similar view in vertical section.

Figure 3 is a section on line 38 of Figure 1.

Figure A is a view similar to Figure 1, the shutter being removed.

Figure 5 is an elevational view of the stove pipe, the draft control being removed, and

Figure 6 is a plan view of the damper and associated parts, said damper being shown in closed position and the pipe being in section.

Figure7 is a perspective view of the damper frame.

Figure 8 is an enlarged section through the shutter and two of the tongues associated therewith, adjacent parts being shown in section also.

Figure 9 is a section on line 99, Figure 5.

Like reference characters indicate like parts throughout the following specification and in the several views in the drawings, in which 1 indicates a section of stove or furnace pipe in which is provided an opening 2; surrounding which is a damper frame 3 having vertical retainer bars a and 5, and a cutout portion 6 in the upper edge of the bar 7 of the frame. Projected upwardly from the bar 7 are a pair of offset tongues 8 and 9, there being a similarly aligned pair of tongues, 10 and 11, depending from the bar 12 of said frame, the upper tongues, 8 and 9 being of about double the length of the lower tongues.

The opening 2 has a pair of slots 12 and 13 in the upper edge portion 14 thereof and another pair of similar slots 15 and 16 are provided in the lower edge portion 17. These latter slots 15 and 16 have their lower edges inclined as shown at 18 and 19 whereby the tongues 10 and 11 can readily be guided into the slots.

lVhen it is desired to place the frame in its opening 2, the tongues 8 and 9 are inserted upwardly into the slots 12 and 13. Thereafter the lower bar 12 of the frame is forced against the stove pipe, thereby causing the lower tongues 10 and 11 to enter the slots 15 and 16. The frame is subsequently forced downwardly so that tongues 10 and 11 will engage the inclined portions 18 and 19. As the tongues 8 and 9 are longer than the tongues 10 and 11, they will not withdraw from engagement with the upper edges 22 and 23 of the slots 12 and 13 during this downward movement of the frame. The tongues 8, 9, 10, and 11 are oifsetto such an extent that when the frame is thrust downwardly as explained it will be caused to bind tightly against the edge portions of the opening 2 so that a tight joint is thus made. The shutter 24 carried by the frame has extensions 25 at the upper edge 27 thereof adapted to conceal the slots 12 and 13 and the tongues 8 and 9 extending thereinto.

Having described my invention, that which I claim to be new and desire to protect by Letters Patent is:

1. In a device as described, a pipe section having a side opening with slots leading therefrom,and a damper frame and tongues thereon adapted to pass through said slots and engage the inner surface of the pipe to hold the frame in said opening.

2'. In a device as described a pipe section having a side opening with slots leading therefrom, and a damper frame and tongues thereon adapted to pass through said slots and engage the inner surfaceof the pipe to hold the frame in said opening, certain of said tongues being longer than others thereof.

3. In a device as described a pipe section having a side opening with slots leading therefrom, and a damper frame and tongues thereon adapted to pass through said slots and engage the inner surface of the pipe to hold the frame in said opening, certain of said tongues being longer than others thereof, said slots leading from the upper and lower edges surrounding said opening.

4. In a device as described a pipe section having a side opening with slots leading therefrom, and a damper frame and tongues thereon adapted to pass through said slots and engage the inner surface of the pipe to hold the frame in said opening, certain of said tongues being longer than others thereof, said tongues being offset from the frame.

5. In combination with a stove pipe having a side opening therein, a frame for the opening and means 011 the frame \v iereby it may be secured to the pipe, said pipe having slots projecting from said opening, said frame having tongues projecting therefrom, and adapted to pass through the slots, and engage the inner side of the pipe to form said se- 15 curing means, and a slide door in said frame. In testimony whereof I afiix my signature.
